Abstract
In this chapter, we will first explain the issues of the current static spectrum licensing approach of spectrum management. This is the source of the spectrum usage paradox: spectrum resource is scarce but much of it is severely under-utilized. This motivates the study of cognitive radio technology and dynamic spectrum access. Dynamic spectrum access aims to improve spectrum utilization through innovations in technology, economics, and policies. We will introduce different types of dynamic spectrum access, in particular, the dynamic exclusive use model and the hierarchical access model. Finally, we will provide a brief overview of the related work.

Notes
- 1.
To become a license holder of certain spectrum band, one needs to wait till the next round of spectrum auction organized by the governmental agency.

There are multiple types of spectrum sensing techniques, e.g., the traditional energy detection which can be easily deployed, the cooperative detection to resolve hidden terminal problem, and the interference-based detection to better manage interference at the primary receivers [4].
